More discrete R2R Mulibit dacs.

There are many now going to the trouble of doing discrete R2R Mulitbit now that the last/latest Burr Brown PCM1704 multibit chip is no longer available "rip".

Yep, and they stopped making them years ago, because Delta Sigma was more than 20 x cheaper to make and allowed for dsd use, probably because there was no laser trimming to be done like in an r2r ladder multibit dac, the last true ladder mulitbit being the Burr Brown PCM1704. It was only 24/96 this thing above can do 24/382 Cheers George
